Production
Titanium alloys are classified according to the configuration of crystal lattices: α-grill — in the form hexahedron), β — in the form of a cube, α + β — mixed state. Alloys OT-4, and OT4−0 OT4−1 are pseudo-alpha alloys. These alloys thermally not harden and are divided into two groups: 1) low-strength high-tech and 2) high-strength super α-alloys. The former contain a small percentage of aluminum and small concentrations of β-stabilizers, which allows to maintain high processability close to that of pure titanium processability. These alloys are well welded all types of welding.
| Alloy | Aluminum | Manganese | Al equivalent% | Mo equivalent% |
|---|---|---|---|---|
| OT4−0 | 0.8 | 0.8 | 1.8 | 1.3 |
| OT4−1 | 0.5 | 1 | 2.5 | 1.7 |

| Alloy | Houde. the weight | t ° mp. | properties | Technology | application |
|---|---|---|---|---|---|
| OT4−0 | 4.51 g / cm³ | 860−930 ° | Low strength and high technology. Manganese improves hot workability during processing pressure | Easily deformed in the hot and cold state, it is possible stamping at room temperature and good welds. | Vysokotehnolo-tech parts for cold stamping. |
| OT4−1 | 4.55 g / cm³ | 910−950 ° | The average strength and high technology | Easily deformed in the hot and cold, good welds all types of welding. | Constructional and sheathing ma-terial, subtlety-related parts of complex shapes. |
| OT4 | 4.55 g / cm³ | 920−960 ° | Medium strength. Increased content of Al increases the strength, but reduces the processability. | Easily deformed in the hot state and is limited in the cold. Stamping is possible heated. Good welds. | Constructional and sheathing material, stamping parts samoltov and GTE, working long to 400 ° |
From alloys FROM-4, and OT4−0 OT4−1 produce semi-finished products such as sheet, strip, bars, rods, forgings, stampings. Pipes and wires are manufactured mainly from OT4−0, OT4−1. as the panel is made from OT4, hollow profiles and ring the details.

disadvantages
RT-alloys have a relatively low strength and a greater inclination to hydrogen embrittlement.
application
High structural efficiency — corrosion, erosion resistance, ballistic resistance and a number of other advantages marks RT-4, OT4−0, OT4−1 determine the feasibility of their use in the manufacture of systems of transportation of nuclear power plants, ship heat exchangers, pumps, systems of ship exhaust pipes and chimneys, water brakes catapults, reflectors explosive jets, systems of vertical shutter release and other similar details. Tubes of these alloys are indispensable in the nuclear energy sector and the chemical industry.
